Today we introduce Aluminum zinc sheet plate to buyers. Compared with galvanized sheet, aluminum zinc sheet plate refers to the addition of aluminum on the basis of zinc to the steel plate coating. Therefore, the corrosion resistance of the aluminum sheet plate is not only 2-5 times that of the galvanized sheet, but also has the high temperature corrosion resistance of the aluminum sheet. Aluminum zinc sheet plate is mainly used for building roofs, walls, home appliances, automobiles, color-coated substrates, etc. Not only because of its good corrosion resistance, but also because the surface of the aluminum zinc sheet plate is smooth and good in appearance.

The composition of the Aluminum zinc sheet plate is 55% aluminum, 43.5% zinc, and 1.5% silicon. Such a composition makes its corrosion resistance much higher than that of galvanized sheet. However, the forming and weldability of the aluminum sheet plate coating are poor. The structure of the aluminum zinc sheet plate is composed of a base plate, a 55% aluminum-zinc plate, an aluminum-zinc coating and an alloy layer. The substrate of aluminum sheet plate generally uses cold-rolled steel plate, which has the advantages of high strength, easy processing and low price.

Analysis of corrosion resistance of aluminum zinc sheet plate coating: from top to bottom are zinc-rich area, aluminum-rich area, silicon particles, alloy layer. The zinc-rich region provides sacrificial protection, and the aluminum-rich region provides passivation protection. The corrosion resistance of the aluminum zinc sheet plate benefits from the protection of the zinc-rich area and the aluminum-rich area.

The effect of coating weight of aluminum zinc sheet plate on corrosion resistance. We know that the weight of the coating is the guarantee of the corrosion resistance of the steel plate, the greater the thickness, the better the corrosion resistance. The following analyzes the influence of some environments on the zinc layer of the aluminum zinc sheet plate. In indoor environments, the coating is AZ70 or AZ100, in suburban environments, AZ150, in urban or industrial areas, AZ150, in coastal areas, AZ180.

Henan Jianhui Steel Co.,Ltd specializes in the production of aluminum zinc sheet plate for many years, the coating weight is guaranteed to be above the standard, and the price is affordable. Welcome to inquire.
